Product Description:
The PMB33E-10114-03 is a brushless servomotor in the PMB Brushless Servomotors series produced by Pacific Scientific. Built for use with servo drives and precision mechanical stages, the unit converts electrical power into tightly regulated rotary motion. In automation lines, it positions loads accurately at programmed speeds and accelerations so machine cycles can run without overshoot or drift. That makes it suitable for indexing tables, packaging axes, and other motion systems that depend on repeatable servo response.
The motor frame follows the NEMA Size 34 standard, so its mounting holes and pilot diameter align with common U.S. servo gearboxes and brackets. A stack length multiple of 3 increases the active lamination height and raises torque density while keeping the exterior footprint unchanged. During closed-loop hold conditions, the winding can sustain 7.4 ARMS at 240 VAC, a value that helps determine drive current capacity and cable size. Rotor position is reported by an optical encoder that outputs 2048 ppr, giving the control loop fine angular resolution for smooth low-speed motion. Because the feedback device also generates electronic commutation tracks, its digital encoder with commutation arrangement removes the need for separate Hall sensors.
Power and feedback conductors exit the housing through flying leads with AMP connectors, which allows cable routing and termination without opening the motor enclosure. The output spindle uses a round shaft that mates with clamp couplings and avoids keyway stress concentrations. For exposed installations, the optional shaft seal and PTC thermistor help block contaminants and provide temperature input to the drive. The combination of encoder feedback, commutation support, and thermal sensing allows the motor to remain part of a closed-loop axis without extra feedback devices mounted on the frame. This motor is intended for use with compatible Pacific Scientific power stages that accept the feedback and thermal-monitoring connections used by the unit.
